The cylinders are driven by intermediate gears 'gl h', which are also put in motion by the driveshaft s, through suitable bevel-gears or other equivalent means. It is necessary that the gears g vh g h be so proportioned that the speed of the inner cylinder shall be greater than that of the outer one by at least one revolution during the time occupied in binding a bundle. The cylinder B is provided with clamps l and m, by which the ends of the band are held during the process of twisting, and a knife, 7.o, for cutting ofi' the latter after being clamped. The clamp l works upon a pivot in a horizontal slot in B, and its shank t projects outward, so as to come in contact with the inner periphery of the cylinder D, by which contact the clamp is forced to compress the end of the band against the side of B, as indicated in Fig. l, except at a certain point, where a slot, w', Fig. 4, is cut through D, and lthe shank l. i ,Is` @LMANEYArSGmBNERa oflohesterfin the county ofiMonroeand StateofNew York, have inventedkcertain lmprovementslin FfMachines for Bindin gGraimf? -`oiwhicllv the followf MPRQV'EMENT"INLGRNWBINDERS- VSpeci.flication forming partof .Letters-Patent No; l 07,823, dated lSeptember `27, 1870.

JThef clamp m is pivoted, so as to work vertically, or nearly so,.in a slot formed in B,`and 1 `is retainedxinits upward position by aspring applied, in any convenientmanner.

An an- `11ular.cam,F,is secured to the interior of the cylinder D, againstwhich the bent arm oi' the clamp m bears during a certainportion of the timerequired tobinda bundle. l is-pivoted, so as to pass through avhorizontal slot in thezcylinder B, and `is held in its outlward position by a suitable spring.` A stop cream, n, is so located within the cylinder D as to force the blade of the knife across the ,inner cylinder, thus severing the band.

` It will be observed that, since the motion of Vthe inner cylinder is quicker than that of the outer one, the clamps l and m and knife k will be operated as often as B gains a revolution upon D..4 The object of this arrangement is to admit'ofv the ends of the band being given several twists,.sincc,iij the cylinder D were stationary, the clamps andknife would` be operated at each revolution of B.

The gear Gis so proportioned that two revolutions are given to the pinion f by the toothed portion of the former, While the crank d is held in the position in which it is left during the remainder of the revolution of G, by means of the spring p, Figs. 1 and 3, or other suitable stop, a recess in which catches and retains the end ,of the crank.

For the purpose of tucking the ends of the band into the bundle, I provide the bent arm G, around which a spring, t, is arranged to return it to its upward position. The pinion q is attached to the extremity of G, and meshes into the segmental gear r, secured to the intermediate gears g h'. The arm G is provided with suitable bearings on the frame of the machine, and has also a sin gle-toothed ratchet, d', in which the pivoted spring-pawl a engages. The pin c', secured at the proper point upon the intermediate gear g', comes in contact with the outer end oi paWl a', thus releasing the tucker to the action of the spring t. The compressor K is pivoted at a convenient point upon the frame of the machine, and is forced down simultaneously with the band-carrier by means of the connecting-link o. The object et" this is to compress the bundle lying upon the platform H when the band is being passed around it.

The operation of my invention is as follows: rlhe band, which has been previously prepared by twisting it from straw or other similar material, and wound upon a reel for use, is passed through the carrier A, and allowed to project somewhat from the lower end. When the shaft s is revolved, the carrier descends by the action of the crank d and connections,

and, when at the lower end of its stroke, theend of band is caught by the clamp l, the cylinders B and D being so timed and arranged with respect to each other and the band-carrier that, by means of the quicker motion of B, the shank t is forced past the slot fr in D, and the clamp thus pressedY against the side of B at the proper time. While, however, the shaft s is making a partial revolution, the band-carrier descends twice by means of the small gear f, and between such decents the grain is 'raked upon thev platform against the band by any suitable raking device. Consequently,`by the second descent of A, the band is passed around the bundle, and, as the former reaches the extremity of its second stroke, the jaw m is folded down upon the band against the plate l by means of the cam F. When A begins to rise, the knife k is forced across the cylinder B by its shank coming in contact with the stop a, and the band thus severed. The twisting-cylinders now make two or more revolutions, according to the proportions of the gears g 7L g h', the ends of the band being firmly twisted together. At this juncture the cylinder B has gained a revolution upon D, and the clamp l is released by its shank dropping through the slot and also the jaw m, by its bent arm,

leaving thecam F, while at the same instant the pawl d is tripped by-the pin c', and the tucker G forced to push the ends of the band into the bundle by means of the spring t. The sheaf is then removed from the .machine by any suitable device.

The compressor K is adjustable to heavy and light grain, by placing the end of the link ,o in any of the holes shown in the lever c.

It may be desirable to provide a spring or other device to check the paying out of the band through the carrier A, so as to regulate the tension around the bundle.

.Instead of the pinion f and gear C, it would be practicable to substitute a cam on the face of the disk C,`so formed as to communicate the proper motions to the carrier A.

What I claim as my invention is- 1. A band-twister, composed of the cylinders B and D, constructed and arranged to operate substantially as described.

2. The revolving cylinder B, provided with clamps Z and on, for holding the ends of the band, and a knife for severing the same, all the parts being constructed to operate substantially as and for the purposes set forth.

3. The segmental gear Gand pinion f, in combination with the reciprocating band-carrier A, when arranged to operate conjointly witn the twisting-cylinders B and D, for the purposes set forth.

4. The hollow reciprocating band-carrier A, in combination with the twisting-cylinders B and D, operating substantially as set forth.
